    I've been experiencing random Kernal Panics on Parallels v.924229 that seem to be rooted in it's virtual memory handling. I believe the issue to be a bug in the latest revision of Parallels and I'm trying to figure out the best way to submit my report to their team.

    I'll leave some detail here, and hopefully someone can help direct me to the proper support channels:

    Code:
    Mon Apr 14 09:54:48 2014panic(cpu 2 caller 0xffffff80092c4f7a): "pmap_enter: pte page not in object"@/SourceCache/xnu/xnu-2422.90.20/osfmk/i386/pmap_x86_common.c:911

    The Kernal Panic seems to refer to the following Apple open source code. Where to my interpretation Parallels is trying to delete paging information that doesn't exist. To me this sounds like it's a bug in the latest revision of Parallels. Sadly the Kernal Panics result in a hard boot of my machine which severely impede my productivity.

    Code:
    [COLOR=#000000]    if (delpage_pm_obj) {[/COLOR]
    
            vm_page_t m;
            vm_object_lock(delpage_pm_obj);
            m = vm_page_lookup(delpage_pm_obj, delpage_pde_index);
            if (m == VM_PAGE_NULL)
                panic("pmap_enter: pte page not in object");
            VM_PAGE_FREE(m);
            OSAddAtomic(-1,  &inuse_ptepages_count);
            vm_object_unlock(delpage_pm_obj);
     [COLOR=#000000]    }
    [/COLOR]
